first is an authentication request by the client that contains the station ID (typically

the MAC address). This is followed by an authentication response from the

AP/router containing a success or failure message. An example of when a failure

may occur is if the client's MAC address is explicitly excluded in the AP/router

configuration.

(2) Shared: Shared key authentication relies on the fact that both stations taking part

in the authentication process have the same "shared" key or passphrase. The

shared key is manually set on both the client station and the AP/router. Three types

of shared key authentication are available today for home or small office WLAN

environments.

(3) Auto: The AP will Select the Open or Shared by the client’s request automatically.

3.2 Forwarding Rules



3.2.1. Virtual Server

This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so

all hosts behind this product are invisible to the outside world. If you wish, you can make

some of them accessible by enabling the Virtual Server Mapping.

A virtual server is defined as a Service Port, and all requests to this port will be

redirected to the computer specified by the Server IP. Virtual Server can work with

Scheduling Rules, and give user more flexibility on Access control. For the details,

please refer to Scheduling Rule.

There is well known services as below, if your service is not included, please configure it

manually.



For example, if you have an FTP server (port 21) at 192.168.1.1, a Web server (port 80)

at 192.168.1.2, and a PPTP VPN server at 192.168.1.6, then you need to specify the

following virtual server mapping table:

Service Port Server IP Enable

21 192.168.1.1 V

80 192.168.1.2 V

1723 192.168.1.6 V


3.2.2. Special AP

Some applications require multiple connections, like Internet games, Video

conferencing, Internet telephony, etc. Because of the firewall function, these

applications cannot work with a pure NAT router. The Special Applications feature

allows some of these applications to work with this product. If the mechanism of Special

Applications fails to make an application work, try setting your computer as the DMZ

host instead.



1. Trigger: The outbound port number issued by the application.

2. Incoming Ports: When the trigger packet is detected, the inbound packets sent to

the specified port numbers are allowed to pass through the firewall.

There is a Popular applications as below, if your application is not included, please

configure it manually.

This device provides some predefined settings. Select your application and click “Copy

to” to add the predefined setting to your list.




3.2.3. Miscellaneous

1. IP Address of DMZ Host

DMZ (Demilitarized Zone) Host is a host without the protection of firewall. It allows a

computer to be exposed to unrestricted 2-way communication for Internet games,

Video conferencing, Internet telephony and other special applications.

2. UPnP Setting

The device supports the UPnP function. If the OS of your client computer supports

this function, and you enabled it, like Windows XP, you can see the following icon

when the client computer gets IP from the device.


3.2.4. IP CAM After you plug AirLive IP Camera into PnP Router, please check the IP CAM table list as following.



3.3 Security Setting

3.3.1. Status

To view the status of security settings for outbound filter, inbound filter and domain filter.



Click on “Refresh” to refresh the webpage.

3.3.2. Packet Filters

Packet Filter includes both outbound filter and inbound filter. And they have same way to

setting.

Packet Filter enables you to control what packets are allowed to pass the router.

Outbound filter applies on all outbound packets. However, inbound filter applies on

packets that destined to Virtual Servers or DMZ host only. You can select one of the two

filtering policies:

1. Allow all to pass except those match the specified rules

2. Deny all to pass except those match the specified rules



You can specify 8 rules for each direction: inbound or outbound. For each rule, you can

define the following:

• Source IP address

• Source port

• Destination IP address

• Destination port

• Protocol: TCP or UDP or both.

• Use Rule#

For source or destination IP address, you can define a single IP address (4.3.2.1) or a

range of IP addresses (4.3.2.1-4.3.2.254). An empty implies all IP addresses.



For source or destination port, you can define a single port (80) or a range of ports

(1000-1999). Add prefix "T" or "U" to specify TCP or UDP protocol. For example, T80,

U53, U2000-2999, No prefix indicates both TCP and UDP are defined. An empty implies

all port addresses. Packet Filter can work with Scheduling Rules, and give user more

flexibility on Access control. For Detail, please refer to Scheduling Rule.

Each rule can be enabled or disabled individually.


3.3.3. Domain Filters

Domain Filter prevents users under this device from accessing specific URLs.



1. Domain Filter: Check if you want to enable Domain Filter.

2. Log DNS Query: Check if you want to log the action when someone accesses the

specific URLs.

3. Privilege IP Address Range: Setting a group of hosts and privilege these hosts to

access network without restriction.

4. Domain Suffix: A suffix of URL can be restricted, for example, ".com", "xxx.com".

5. Action: When someone is accessing the URL met the domain-suffix, what kind of

action you want.

Check “Drop” to block the access. Check “Log” to log this access.

6. Enable: Check to enable each rule.




3.3.4. URL Blocking

URL Blocking will block LAN computers to connect with pre-define Websites. The

major difference between “Domain filter” and “URL Blocking” is Domain filter require

user to input suffix (like .com or .org, etc), while URL Blocking require user to input a

keyword only. In other words, Domain filter can block specific website, while URL

Blocking can block hundreds of websites by simply a keyword.

1. URL Blocking: Check if you want to enable URL Blocking.

2. URL: If any part of the Website's URL matches the pre-defined word, the connection

will be blocked.

For example, you can use pre-defined word "sex" to block all websites if their URLs

contain pre-defined word "sex".

3. Enable: Check to enable each rule.




3.3.5. MAC Control

MAC Address Control allows you to assign different access right for different users and to

assign a specific IP address to a certain MAC address.

1. MAC Address Control: Check “Enable” to enable the “MAC Address Control”. All

of the settings in this page will take effect only when “Enable” is checked.

2. Connection control: Check "Connection control" to enable the controlling of

which wired and wireless clients can connect with this device. If a client is denied to

connect with this device, it means the client can't access to the Internet either.

Choose "allow" or "deny" to allow or deny the clients, whose MAC addresses are

not in the "Control table" (please see below), to connect with this device.

3. Association control: Check "Association control" to enable the controlling of

which wireless client can associate to the wireless LAN. If a client is denied to

associate to the wireless LAN, it means the client can't send or receive any data via

this device. Choose "allow" or "deny" to allow or deny the clients, whose MAC

addresses are not in the "Control table", to associate to the wireless LAN.





1. Administrator Time-out: The time of no activity to logout automatically, you may set

it to zero to disable this feature.

2. Remote Administrator Host/Port:

In general, only Intranet user can browse the built-in web pages to perform

administration task. This feature enables you to perform administration task from

remote host. If this feature is enabled, only the specified IP address can perform

remote administration. If the specified IP address is 0.0.0.0, any host can connect

with this product to perform administration task. You can use subnet mask bits "/nn"

notation to specified a group of trusted IP addresses for example, "10.1.2.0/24".

NOTE: When Remote Administration is enabled, the web server port will be shifted

to 80. You can change web server port to other port, too.

3. Discard PING from WAN side: When this feature is enabled, any host on the WAN

cannot ping this product.

4. DoS Attack Detection: When this feature is enabled, the router will detect and log

3.4.2. System Log

This page supports two methods to export system logs to specific destination by means

of syslog (UDP) and SMTP (TCP). The items you have to setup including:

1. IP Address for Sys log: Host IP of destination where sys log will be sent to. Check

Enable to enable this function.

2. Setting of Email alert: Enable Email alert (send syslog via email).

3. SMTP Server IP and Port: Input the SMTP server IP and port, which are connected

with ':'. If you do not specify port number, the default value is 25.

For example, "mail.your_url.com" or "192.168.1.100:26".

4. E-mail addresses: The recipients who will receive these logs, you can assign more

than 1 recipient, using ';' or ',' to separate these email addresses.

5. E-mail Subject: The subject of email alert, this setting is optional.




3.4.3. Dynamic DNS

To host your server on a changing IP address, you have to use dynamic domain name

service (DDNS). So that anyone wishing to reach your host only needs to know the

name of it. Dynamic DNS will map the name of your host to your current IP address,

which changes each time you connect your Internet service provider.

Before you enable Dynamic DNS, you need to register an account on one of these

Dynamic DNS servers that we list in Provider field.

To enable Dynamic DNS click the check box next to Enable in the DDNS field. Next

you have to enter the appropriate information about your Dynamic DNS

Serve .Provider, Host Name, Username/E-mail, and Password/Key. You can get this

information when you register an account on a Dynamic DNS server.




3.4.4. QOS

Provide different priority to different users or data flows, or guarantee a certain level of

performance.

1. QOS Control: Check Enable to enable this function.

2. Bandwidth of Upstream: Set the limitation of upstream bandwidth

3. Local IP : Ports: Define the Local IP address and ports of packets

4. Remote IP : Ports: Define the Remote IP address and ports of packets

5. QoS Priority: This defines the priority level of the current Policy Configuration.

Packets associated with this policy will be serviced based upon the priority level set.

For critical applications High or Normal level is recommended. For non-critical

applications select a Low level.

6. Enable: Check to enable the corresponding QOS rule.

7. User Rule#: The QoS rule can work with Scheduling Rule number#. Please refer to

the Section 3.1.4.7 Schedule Rule.




3.4.5. SNMP

In brief, SNMP, the Simple Network Management Protocol, is a protocol designed to

give a user the capability to remotely manage a computer network by polling and setting

terminal values and monitoring network events.

1. Enable SNMP: You must check “Local”, “Remote” or both to enable SNMP function.

If “Local” is checked, this device will response request from LAN. If “Remote” is

checked, this device will response request from WAN.

2. Get Community: The community of GetRequest that this device will respond.

3. Set Community: The community of SetRequest that this device will accept.

4. IP 1, IP 2, IP 3, IP 4: Enter the IP addresses of your SNMP Management PCs. User

has to configure to where this device should send SNMP Trap message.

5. SNMP Version: Select proper SNMP Version that your SNMP Management

software supports.

6. WAN Access IP Address: If you want to limit the remote SNMP access to specific

computer, please enter the PC’s IP address. The default value is 0.0.0.0, and it

means that any internet connected computer can get some information of the device

with SNMP protocol.




3.4.6. Routing

If you have more than one routers and subnets, you will need to enable routing table to

allow packets to find proper routing path and allow different subnets to communicate

with each other. The routing table allows you to determine which physical interface

address to use for outgoing IP data grams.

1. Dynamic Routing: Routing Information Protocol (RIP) will exchange information

about destinations for computing routes throughout the network. Please select

RIPv2 only if you have different subnet in your network. Otherwise, please select

RIPv1 if you need this protocol.

2. Static Routing: For static routing, you can specify up to 8 routing rules. You can

enter the destination IP address, subnet mask, gateway, and hop for each

routing rule, and then enable or disable the rule by checking or un-checking the

Enable checkbox.




3.4.7. System Time

1. Time Zone: Select a time zone where this device locates.

2. Auto-Synchronization: Check the “Enable” checkbox to enable this function.

Besides, you can select a NTP time server to consult UTC time.

3. Sync with Time Server: Click on the button if you want to set Date and Time by

NTP Protocol manually.

4. Sync with my PC: Click on the button if you want to set Date and Time using PC’s

Date and Time manually.

. Click on “Save” to store your settings or click “Undo” to give up the changes.



3.4.8. Scheduling

You can set the schedule time to decide which service will be turned on or off.

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

Everyone is permitted to copy and distribute verbatim copies

of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and

change it. By contrast, the GNU General Public License is intended to guarantee your

freedom to share and change free software--to make sure the software is free for all its

users. This General Public License applies to most of the Free Software Foundation's

software and to any other program whose authors commit to using it. (Some other Free

Software Foundation software is covered by the GNU Library General Public License

instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public

Licenses are designed to make sure that you have the freedom to distribute copies of free

software (and charge for this service if you wish), that you receive source code or can get it

if you want it, that you can change the software or use pieces of it in new free programs;

and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these

rights or to ask you to surrender the rights. These restrictions translate to certain

responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you

must give the recipients all the rights that you have. You must make sure that they, too,

receive or can get the source code. And you must show them these terms so they know

their rights.



We protect your rights with two steps: (1) copyright the software, and (2) offer you this

license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone

understands that there is no warranty for this free software. If the software is modified by

someone else and passed on, we want its recipients to know that what they have is not the

original, so that any problems introduced by others will not reflect on the original authors'

reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the

danger that redistributors of a free program will individually obtain patent licenses, in effect

making the program proprietary. To prevent this, we have made it clear that any patent must

be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the

copyright holder saying it may be distributed under the terms of this General Public License.

The "Program", below, refers to any such program or work, and a "work based on the

Program" means either the Program or any derivative work under copyright law: that is to

say, a work containing the Program or a portion of it, either verbatim or with modifications

and/or translated into another language. (Hereinafter, translation is included without

limitation in the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by this License;

they are outside its scope. The act of running the Program is not restricted, and the output

from the Program is covered only if its contents constitute a work based on the Program

(independent of having been made by running the Program). Whether that is true depends

on what the Program does.



1. You may copy and distribute verbatim copies of the Program's source code as you

receive it, in any medium, provided that you conspicuously and appropriately publish on

each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the

notices that refer to this License and to the absence of any warranty; and give any other

recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option

offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a

work based on the Program, and copy and distribute such modifications or work under the

terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed

the files and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains

or is derived from the Program or any part thereof, to be licensed as a whole at no

charge to all third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run, you must

cause it, when started running for such interactive use in the most ordinary way, to print

or display an announcement including an appropriate copyright notice and a notice that

there is no warranty (or else, saying that you provide a warranty) and that users may

redistribute the program under these conditions, and telling the user how to view a copy

of this License. (Exception: if the Program itself is interactive but does not normally print

such an announcement, your work based on the Program is not required to print an

announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that

work are not derived from the Program, and can be reasonably considered independent

and separate works in themselves, then this License, and its terms, do not apply to those

sections when you distribute them as separate works. But when you distribute the same

sections as part of a whole which is a work based on the Program, the distribution of the

whole must be on the terms of this License, whose permissions for other licensees extend

to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written

entirely by you; rather, the intent is to exercise the right to control the distribution of

derivative or collective works based on the Program.



In addition, mere aggregation of another work not based on the Program with the Program

(or with a work based on the Program) on a volume of a storage or distribution medium

does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in

object code or executable form under the terms of Sections 1 and 2 above provided that

you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code,

which must be distributed under the terms of Sections 1 and 2 above on a medium

customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for

a charge no more than your cost of physically performing source distribution, a complete

machine-readable copy of the corresponding source code, to be distributed under the

terms of Sections 1 and 2 above on a medium customarily used for software

interchange; or,

c) Accompany it with the information you received as to the offer to distribute

corresponding source code. (This alternative is allowed only for noncommercial

distribution and only if you received the program in object code or executable form with

such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modifications

to it. For an executable work, complete source code means all the source code for all

modules it contains, plus any associated interface definition files, plus the scripts used to

control compilation and installation of the executable. However, as a special exception,

the source code distributed need not include anything that is normally distributed (in either

source or binary form) with the major components (compiler, kernel, and so on) of the

operating system on which the executable runs, unless that component itself accompanies

the executable.

If distribution of executable or object code is made by offering access to copy from a

designated place, then offering equivalent access to copy the source code from the same

place counts as distribution of the source code, even though third parties are not compelled

to copy the source along with the object code.



4. You may not copy, modify, sublicense, or distribute the Program except as expressly

provided under this License. Any attempt otherwise to copy, modify, sublicense or

distribute the Program is void, and will automatically terminate your rights under this

License. However, parties who have received copies, or rights, from you under this License

will not have their licenses terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However,

nothing else grants you permission to modify or distribute the Program or its derivative

works. These actions are prohibited by law if you do not accept this License. Therefore,

by modifying or distributing the Program (or any work based on the Program), you indicate

your acceptance of this License to do so, and all its terms and conditions for copying,

distributing or modifying the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the

recipient automatically receives a license from the original licensor to copy, distribute or

modify the Program subject to these terms and conditions. You may not impose any

further restrictions on the recipients' exercise of the rights granted herein. You are not

responsible for enforcing compliance by third parties to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or for any

other reason (not limited to patent issues), conditions are imposed on you (whether by court

order, agreement or otherwise) that contradict the conditions of this License, they do not

excuse you from the conditions of this License. If you cannot distribute so as to satisfy

simultaneously your obligations under this License and any other pertinent obligations, then

as a consequence you may not distribute the Program at all. For example, if a patent

license would not permit royalty-free redistribution of the Program by all those who receive

copies directly or indirectly through you, then the only way you could satisfy both it and this

License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular

circumstance, the balance of the section is intended to apply and the section as a whole is

intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property

right claims or to contest validity of any such claims; this section has the sole purpose of

protecting the integrity of the free software distribution system, which is implemented by

public license practices. Many people have made generous contributions to the wide

range of software distributed through that system in reliance on consistent application of



that system; it is up to the author/donor to decide if he or she is willing to distribute software

through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of

the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries either by

patents or by copyrighted interfaces, the original copyright holder who places the Program

under this License may add an explicit geographical distribution limitation excluding those

countries, so that distribution is permitted only in or among countries not thus excluded. In

such case, this License incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the General

Public License from time to time. Such new versions will be similar in spirit to the present

version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies a version

number of this License which applies to it and "any later version", you have the option of

following the terms and conditions either of that version or of any later version published by

the Free Software Foundation. If the Program does not specify a version number of this

License, you may choose any version ever published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs whose

distribution conditions are different, write to the author to ask for permission. For software

which is copyrighted by the Free Software Foundation, write to the Free Software

Foundation; we sometimes make exceptions for this. Our decision will be guided by the

two goals of preserving the free status of all derivatives of our free software and of

promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO

WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE

LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS

AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY

OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,



THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A

PARTICULAR PURPOSE.

THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS

WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST

OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY

MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE

TO YOU FOR DAMAGES,

INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES

ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT

NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR

LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM

TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER

PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
